On the way to Jerusalem he was passing along between Samaria and Galilee. ¹² And as he entered a village, he was met by ten lepers, who stood at a distance ¹³ and lifted up their voices, saying, “Jesus, Master, have mercy on us.” ¹⁴ When he saw them he said to them, “Go and show yourselves to the priests.” And as they went they were cleansed. ¹⁵ Then one of them, when he saw that he was healed, turned back, praising God with a loud voice; ¹⁶ and he fell on his face at Jesus' feet, giving him thanks.  Now he was a Samaritan. ¹⁷ Then Jesus answered, “Were not ten cleansed?  Where are the nine? ¹⁸ Was no one found to return and give praise to God except this foreigner?” ¹⁹ And he said to him, “Rise and go your way; your faith has made you well.”
